As I suspected, the b partition is for swap and it is defined by default that
way. There are other ways to define extra swap in the file system as well. I
also got a lot of good comments about tools to use to look for the swap...If
you are really interested, I can forward the replies I got. However, one of
the listers gave a url for the "Sun-managers mailing list search engine", i.e.
DATAMAN!
Also mentioned was pstat...
http://www.dataman.nl/cgi-bin/codeprof
and if you search for "sunos disk partitions" the 7th item sums up what I was
looking for... Basically, there are some subtle gotchas here.....
But I'm including the best couple of answers I got....
--------------------------------------------------------------------------------
Surprise! :)
I got bitten by this bug myself; I had put a new disk on a machine and
tried to move the boot partition and others onto it, putting /usr on b, and
then could not access it.
SunOS by default uses the b partition for swap. To the best of my knowledge,
there's no way around it.

How come there are no 'Sendmail for Dummies' books?
--------------------------------------------------------------------------------
By default the SunOS kernel will use the 'b' partition from the
same disk as the root filesystem as a swap device. The swap-type
commands don't display the swap device (they do under Solaris
but that's just one of many improvements).
You can check /etc/fstab to see if there are any other devices
specified of type 'swap' - these will be additional swap
partitions.

Try "dkinfo sd0" and it will tell you some
info about the partitions without having to go into "format".
